First off, a production version of a new X4 model is expected at the New York Auto Show in April. The model was previously rumored to be earmarked for reveal a month earlier, but a new report from Autocar suggests that the previously mooted reveal date and location were inaccurate. The X4 is expected to apply the same controversial slant-back formula to the X3 that transformed the X5 into the X6, which will in turn lead to an update for the X3 as well.
But that's not all. Autocar also reports that before 2014 is out, BMW will unveil a revised X6 at the Moscow Motor Show in August, which will in turn be followed by upgraded versions of both the X6 M and X5 M. These high-performance crossovers are tipped to pack the same 4.4-liter twin-turbo V8 as the outgoing versions, albeit with higher outputs than the current models' 555 horsepower and 500 pound-feet of torque. All this, and they're still expected to simultaneously improve fuel consumption and emissions figures.
